Hoard Robber + Time Sieve + Academy Manufactor + Phantasmal Image

Hoard Robber

Time Sieve

Academy Manufactor

Phantasmal Image

How it works

1. Attack with Hoard Robber.
2. Hoard Robber triggers on combat damage to a player, creating three Treasure tokens, three Food tokens, and three Clue tokens.
3. Activate Time Sieve's ability by tapping Time Sieve and sacrificing five artifacts you control, taking an extra turn after this one.
4. Repeat.

This ingenious extra-turn loop relies on the explosive token-generation engine provided by Academy Manufactor, which turns every single Treasure created by Hoard Robber into a massive trove of nine total artifacts—three Treasures, three Foods, and three Clues. With that wealth of permanent fodder generated every time Hoard Robber connects in combat, you easily exceed the five-artifact requirement demanded by Time Sieve to take extra turns indefinitely. Meanwhile, Phantasmal Image serves as an economical clone that can step in as a copy of Academy Manufactor to double your yield or duplicate Hoard Robber to ensure your combat damage triggers keep the artifact factory running smoothly.
